When it comes to brown fused alumina, everyone first thinks of its hardness and wear resistance, etc., but there is another characteristic of brown fused alumina that is ignored by everyone, and that is its toughness. Today, the editor will take you to briefly understand the toughness of brown fused alumina.
Let’s understand what the concept of toughness is. The toughness of abrasives refers to the ability of abrasive grains to resist crushing under the action of grinding force. It is an attribute of abrasives’ ability to resist impact and absorb energy.
If the brown fused alumina has a certain toughness, it will guarantee its own service life. At the same time, the toughness also has a great influence on the self-sharpening of the brown fused alumina. The stronger the toughness, the less likely the brown fused alumina is to break, but it is easy to passivate and grind. When the power drops, the functions of the two are mutually restraining and killing each other.
Of course, there is also a measure for the toughness of brown fused alumina, which cannot be extended infinitely, because of the contradictory properties of brown fused alumina’s toughness and self-sharpness, so, this requires customers to determine the toughness and self-sharpness according to their own needs. balance.
What is the use of the toughness of brown corundum?
Brown corundum has a certain toughness to ensure its service life. We know that the better the toughness of brown fused alumina, the stronger its resistance to crushing, the less likely it will be broken, and the service life will be extended to a certain extent.
The main factors of the toughness of brown fused alumina:
1. The main component of brown fused alumina is aluminum oxide, and the grade is distinguished by the aluminum content. The lower the toughness, the lower the aluminum content.
2. How much carbon is contained in brown corundum, and low-carbon brown corundum has high toughness.
3. The treatment process of calcined brown corundum. The brown corundum is calcined in a rotary furnace, and then flowed into a vertical furnace for supplementary calcination, so as to prevent the color of the abrasive from fading and the color of the abrasive to become blue-black.
The above is the conceptual function and influencing factors of the toughness of brown fused alumina compiled by the editor. In this regard, I hope the above will help you better understand brown fused alumina.
